damper

The failure rate of Electric Butterfly Damper Valve is very low. It's very convenient to use. And because its sealing system is metal sealing, so the service life is longer than elastic seal, and has the characteristics of high temperature resistance. And Electric Butterfly Damper Valve can also be customized according to the needs of customers

1. Exhaust Gas Smoke Louver Ventilation Butterfly Valve is made of high quality material, which can be well resistant to corrosion, high temperature, oil and acid 2. The surface of Exhaust Gas Smoke Louver Ventilation Butterfly Valve is beautiful and flat, and the professional production process improves the stable performance of the product. It is solid, compact and has a long service life 3. We can customize various specifications according to customers' requirements, and we will provide you with solutions

There are no connecting rod, bolt and other components in its interior, so some component problems will not occur in the use process, so the failure rate is very low. It's very convenient to use. It is a reliable valve device. Because there is a large gap between the butterfly plate and the valve body of Stainless Steel Damper Control Butterfly Valve, there is enough expansion space, so in the process of use, it can effectively prevent the thermal expansion and cold contraction caused by the temperature change, and the butterfly plate will not be stuck. Because of the wide selection of materials, this kind of ventilation butterfly valve also has the characteristics of high temperature resistance, there will be no friction when opening and closing, and the service life is extremely long.

Large Diameter Big Size DN4600 Damper Butterfly Valve is welded with high-quality wear-resistant materials, with good wear resistance, stable and reliable operation, easy operation, sensitive action, small leakage rate, long service life and convenient installation and maintenance. It is especially suitable for low pressure difference, large diameter and large flow occasions. It is used in combination with various actuators to form different performance valves.

In addition to the advantages of general butterfly valve, Ventilation Volume Control Damper has a unique structure. It is welded with high-quality steel plate. Ventilation Volume Control Damper has small volume, light weight, large flow section, flexible opening and closing, convenient use and maintenance, and low price. Ventilation Volume Control Damper can be wafer connection or flange connection.

1.This carbon steel sluice damper is a kind of gate for water supply and drainage and sewage treatment, this wall penstock valve is designed and improved by using advanced structure and technology. 2.The manufacturing and processing of this carbon steel sluice damper valve conforms to CJ / T3006-1992 standard and AWW standard of the United States. 3.This wall penstock valve is widely used in municipal, petroleum, chemical, power station, metallurgy, coal, light industry, food, pharmaceutical, water conservancy, sewage treatment and other water supply and drainage projects, to cut off, dredge the water flow or adjust the water level. 4. This wall penstock valve can be combined with manual, electric and hydraulic hoist to realize field operation or remote centralized control.

▷The google valve plate sealing ring adopts special silicone rubber sealing ring, and the sealing pair is special silicone rubber/stainless steel. The valve plate movement adopts two-way rolling structure. ▷In case of power failure or failure, the google valve can be opened and closed manually on site. ▷The shaft head seal of the transmission shaft of the traverse mechanism adopts the form of packing gland, which is reliable and easy to maintain. ▷The transversal mechanism is located above the valve and adopts stainless steel tooth pin drive, which is wear- resistant, corrosion-resistant and has a long service life.

1. It is convenient and quick to open and close, with low fluid resistance and easy operation. 2. Simple structure, small size, short structure length, small volume, light weight, suitable for large caliber valve. 3. It can transport mud and store the least liquid at the pipe mouth. 4. Under low pressure, good sealing can be achieved. 5. Good regulation performance. 6. When the valve seat is fully open, the effective flow area of the valve seat channel is large and the fluid resistance is small. 7. The opening and closing torque is small, because the butterfly plates on both sides of the rotating shaft are basically equal to each other under the action of medium, and the direction of torque is opposite, so it is easier to open and close. 8. The sealing surface materials are generally rubber and plastic, so the low-pressure sealing performance is good. 9. Easy to install. 10. The operation is flexible and labor-saving. Manual, electric, pneumatic and hydraulic modes can be selected.

There is no connecting rod, bolt and other components in the part, so there will be no component problems in the process of use, so the failure rate is very low. Because there is a large gap between the butterfly plate and the valve body of the ventilation butterfly valve, there is enough expansion space, so in the process of use, it can effectively prevent the thermal expansion and cold contraction caused by the temperature change, and the butterfly plate will not be stuck
